The default report also lists detailed information about the respective events detected at the bottom of the report in the Events table.

Charts

The charts display all data collected for a specific DNS activity event type.

Each green-colored bar on a Requests chart indicates a specific time interval within the chosen time span displayed. By rolling over each bar, the number of events, the time interval, and the date of the bar are displayed in a tool-tip window.

The table, located below the chart displays data collected for the selected DNS activity event type. The default layout is automatically loaded for viewing; however, the table can be customized by adding additional types of report information. To add additional information to a table, click the expandable menu icon to select and display from the other additional information types listed in the option window. By default, events are displayed in chronological order based on information contained within the Detected column. Each of the columns can be sorted or reverse-sorted by clicking on the header label for the column.

Located in the bottom-left corner of the table, the total number of table records is displayed. For instance, if there are 57 records available when unfiltered, then the table will display the following: Showing 57 of 57. If only 48 records are available after applying filters, then the table will display the following: Showing 48 of 57. The maximum number of records the UI can display is 10,000.
